Legacy Product Upgrades

Firmware upgrades for Series 5900, 6000 and 6100 DF processors may be downloaded at no charge by our
customers. The firmware programs are Intel HEX format which can be loaded into a
27C512 EPROM. The EPROM must be at least 120 nsec and should preferably be 90
nsec. You will need an EPROM programmer and, if you plan to use the existing
EPROM, an EPROM eraser.

Series 5900 Upgrades

The older version of the Series 5900 was the DDF5911. It can be identified by
the 15 pin female connector used on the front panel for the RF Summer control
cable. The current version of the Series 5900 is the DDF5931 and it uses a 15
pin male connector for connection to its (different) RF summer.

DDF5911 Upgrades

The firmware used in the processor can
be upgraded by simply replacing or reprogramming the EPROM. The version
displayed in the remote display (DDF5921) when the system is first powered up is
the firmware revision of the remote display itself, which can not be
upgraded.

To determine the version of firmware in your DDF5911, connect the unit to a
PC, run Hyperterm at 4800 8N1, and issue serial command number 32 (identify
software). You can also remove the bottom cover and note the marking on the
EPROM label. Locate the firmware revision in the table below to determine
whether to upgrade.

Check the crystal frequency used in your DDF5911 by removing the bottom
cover. Look for the crystal that is closest to the microprocessor (U105). It
will be either 9.216 or 9.830 MHz.

Download the Intel formatted EPROM HEX file for the latest version of the
firmware. If the crystal is 9.216 MHz, download the file
5911_a.HEX.
If it is 9.830 MHz, download the file
5911A.HEX.

DDF5931 Upgrades

The firmware used in the processor can
be upgraded by simply replacing or reprogramming the EPROM. The version
displayed in the remote display (DDF5921) when the system is first powered up is
the firmware revision of the remote display itself, which can not be
upgraded.

To determine the version of firmware in your DDF5931, connect the unit to a
PC, run Hyperterm at 4800 8N1, and issue serial command number 32 (identify
software). You can also remove the bottom cover and note the marking on the
EPROM label. Locate the firmware revision in the table below to determine
whether to upgrade.

Check the crystal frequency used in your DDF5931 by removing the bottom
cover. Look for the crystal near the microprocessor (U105). It
will be either 9.216 or 9.830 MHz.

Download the Intel formatted EPROM HEX file for the latest version of the
firmware. If the crystal is 9.216 MHz, download the file
5931_a.HEX.
If it is 9.830 MHz, download the file
5931A.HEX.

Series 6000 and 6100 Upgrades

For a nominal charge, we will upgrade the firmware and retest the processor
for you. This is generally best as accessing the EPROM on these units is more
difficult, and it is easy to misidentify the model number and revision of the
hardware. To upgrade the firmware yourself, follow the directions
below:

Firmware versions

To determine whether you want to upgrade, locate the firmware version of your
current model in the following table. This table lists all of the revisions which have been shipped and the changes that have been made. To determine which version you have in your
direction finder, note the first display shown in the bearing window following
power turn-on. The version is displayed as X.XX in the bearing window with a 1
displayed in the S-meter window.

To obtain
a firmware upgrade, you need to identify the hardware version of your
direction finder. The basic model number (DDF6000, DDF6100, DDF6001 or DDF6002)
is marked on the front panel. To determine the revision level of the unit,
remove the top cover and refer to the descriptions and photos shown on the web
page DDF6xxx Identification.

The latest version EPROM program may be obtained by downloading
the HEX file listed in the table.
